Most Unusual Hotels of the World: Radisson Blu in Berlin

Update 12.02.2025: After two years of renovation, the hotel has reopened. Instead of the demolished aquarium in the lobby, there is now a new installation — a 24-metre-high vertical garden known as the ‘Living Tree’. This ‘living wood’ consists of nearly 2,000 plants of 22 species, arranged on 36 vertical pillars, with dynamic lighting that changes throughout the day.

Update 12/16/2022: the aquarium exploded, all the fish died :(

This hotel has one of the best locations in the city, but is famous not because of this. The rooms with balconies which overlook the inner atrium ({{132}}) offer views of the giant Aquadom.






You can open the balcony window and watch the fish, it is very soothing :)


Aquadom is the world's largest cylindrical saltwater aquarium. Its height is 16 m and diameter is 11.5 m.


The volume of the aquarium is 1 million liters, 1,500 fish live inside.


Aquadom can be visited from the inside, there constantly runs a two-story elevator. The entrance to the elevator is made in such a way that tourists do not get into the hotel lobby, they are in a glass tunnel.
